En-spurns Joe Romnsen, or niims w a, use; YORK.

Be it known that 1, Joe Roelxsoai, citizen of? thel nitedfitates,residing at Matteawz'in, in the county of Dutchess and Stateof New York,- h a v e invented certain new and useful Improvements in'l'ieyhcle-Guides, of which the followingis a specification.

The present invention aims to provide ful improvements in face plates or escutcheons for door locks, and has pargr reference to that type of such dewhich are formed the nature of -hcle guides.

i ls-the principal object, therefore, the present invention aims to provide an ornamental face plate or escutcheonfor door locks, forming the device in such a manner that it will serve as a guide when the key is applied to the lock.

-further object to construct the guide plate with such regard to the proportion and number of parts that it may he cheaply nninuiactured, will. he durable and efiicient in is a( ion. and may he readily applied to any ordinary form of lock.

The above and additional objects a-reaccmmlished h such means as are illustratedin the accoiupauying drawings, described in the 'l llmving specification. and then more application.

With reference to the drawings, wherein I have illustrated the preferred embodim nt rl in min ention as it is reduced to practice. and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a per- Proceeding now to the description of the invention and referring particularly to Fig.

1, the preferred embodiment. of this invention consists'esscntially in a body plate 10 which, as shown, is substantially rectangular s in shape.

particularly pointed out in the claim nfhich is appended hereto and Forms a part of this Specification of Letters Patent. Application filed December 17, 1913. Serial No. 5.922%.

eithercast or formed from pressed metal in the velldmown manner. The body plate 10 is formed in, the nature oi a shell which is 'l'i'izsto-pyrainidal in shape. the object in thus forming the body member being to providertlio {our inwardly converging walls 11, 12 13, and ll. it will he noted that the shell or bcdy plate is l'orniod with a. key hole opening 1.) which lies-at the inner portionof the shell. Formed on the outer edges of the walls 13 and ll. which constitute the upper and lower walls of the shell, are a pair of spacing;- lips or walls 16 and 1'? which extend at right'angles to the plane of the outer-edges of the Walls ll, .12, 13, and ll and are bent outwardly and at right angles at their free ends to produce the apertured attaching portions 18 and if). lhe member 18 isiornied centrally on the member 1?, while the member 19 extends the entire length of the member 17, as will be readily observed upon reference to Hi. 1. Upon reference to this figure also, it Will be further noted that the lower edges oi the meml ors l6 and 1? lie in the plane of the inner edges of the walls 1.1, 1'2, 13, and 14, being thus adapted to properly support the body portion or shell 10 against the face of the door. Sci-nus. rivets, or other suitable 'fa'stenin'g, devices, may he applied to the 'attaching' portions 18 and 19 -:'r'(' 'r holding 'thcd'cvice 1n the desired position on the door.

As a means for normally sealing the keyhole opening 15 to prevent the exposure of the lock to the rain, hail, and thelike, there has been provided a pivot closure plate 20 which, as shown, is pret'cral'ily rectangular in shape and formed from sheet brass, copper, or any other desired metal, which is possessed of ornamental and decorative properties. On the upper end of the plate 20 is formed a lug 21 which is provided with a longitudinally extending bore through which is inserted a pivot pin In this connection, it may he observed that, if found desirable, the pivot pin may he also employed as the means for securing the memher 18 to the door. A finger-piece '23 may be secured to the closure plate 20 for the obvious purpose of ei'iahling the operator to swing the closure plate upwardly on its pivot pin so that access maybe had to the key-hole.

in the modification illustrated in Fig. 2,

This body member 10 may be i it will he noted that the key-hole guide plate ill) is substantiallysiznilar tojthe body portion or shell of the preferred form, above described. Inasmuch as the modification of Fig. 2 is designed to be embedded in the face of the door, as will be noted upon reference to Fig. 3, the members 16, 17,18, and 19, and the closure platehave, vof course,- been omitted. It will thus be noted that the modification illustrated in Fi 2 Consists merel in a frusto-pyramidal s ell which is modi ed for the receiving recess formed in the face of the door and operates in the same manner as the preferred form of the device to properly ide the key into the key-hole.

The modi cation illustrated in Fig. 4 is also greatly similar to the preferred form, with the exception that the attaching portions 18 and 19 of the preferred form are elongated to rovide plates and 26. These plates 25 an 26 rendera more ornamental appearance to the device, inasmuch as they may be embossed with the family coat of arms or an appropriate design. When the modification illustrated in Fig. 4 is emefficient in its action, and is so designed that it will lend an ornamental appearance rather than detract from the appearance of the door. ---In reduction to practice, I'have found that the form of-m'y invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desirev to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the'advantages of my invention, as defined in the appended claim.

What I claim is The combination with a lock, of a keyhole guide consisting of a frusto-pyramidal shell having a key-hole at its smaller terminal, the shell being arranged in registration with the key-hole of the lock, end walls formed at the upper and lower edgesof the body member and extendin at right angles to the plane of the outer edges of the body member and in the direction of the lock,

apertured portions extendin outwardly at right angles to the end walls for securing the body member to the supporting surface, a lug extending laterally from one apertured portion and in parallel spaced relation to the adjacent end wall, saidlug being provided with a longitudinal bore, a pivot pinextending through the bore, and a closure plate having its upper terminal pivoted on the outer terminal of the said pin and hearing against the outer terminal of the said n testimony whereof I afiix my signature in presence of two witnesses.
